Explanation:

I’ll pay it
What makes both of them wrong is the fact that they were both abbreviated. In a formal letter, we are supposed to keep everything whatsoever we write formal, and as such, "I'm", in place of "I am" and "I'll" in place of "I will" is quite wrong for a formal letter, since the former is an informal way of writing the later.
Changing both context however, to "I am not happy at all", and "I will pay it" makes it fit into the requirements for a formal letter.
